On April 14, 2025 at 02:25 UTC, a magnitude 4.7 intermediate depth earthquake struck in the Kermadec Islands region, at a depth of 70.6 km and coordinates -27.3009°, -176.7095°. This earthquake was detected by 19 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
